TOY BOAT.

SPECIFICATION forming part of Letters Patent No. 616,410, dated December0, 1

Application filed August 4, 1898.

To aZZ whom, it may concern:

Be it known that I, JOSIAH THOMAS CRAWX LEY, of Honolulu, Hawaii, haveinvented a new and Improved Toy Boat, of which the following is a full,clear, and exact description.

The object of the invention is to provide a new and improved toy boatwhich is simple and durable in construction and designed to be propelledin a very simple manner without the use of special machinery.

The invention consists of novel features and parts and combinations ofthe same, as will ed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in both the figures.

Figure 1 is a side elevation of the improvement with parts in section,and Fig. 2 isa plan view of the same.

The improved toy boat is provided with a completely-closed hull A, aheel l3, and a rudder O of any approved construction, and from the hullA leads a small pipe D in a rearward direction in alinement with thekeel 13, the pipe being preferably located between the end of the keeland the gearing for the rudder, as is plainly indicated in the drawings.The top of the hull A is provided with a filling-opening normally closedby a plug E, and directly below the said filling-opening is arranged atransverse shelf F, adapted to sustain substances for generating gas inthe hull of the boat.

The device is used as follows: The plug E of the filling-opening isremoved,and then the interior of the hull is partly filled with air orother suitable fluid, as indicated in Fig. 1, and a gas-generatin gsubstance is placed on the shelf F and the plug E is screwed into thefilling-opening to close the hull. The gas generated from the substanceon the shelf F now presses upon the liquid contained in the hull, sothat this liquid is forced out in a very fine stream and in a rearwarddirection into the water in which the boat is to be propelled, and asthe stream leaving the pipe D strikes the water it propels the boatforward in a di- Serial No. 687,707.

rection in accordance with the position of the rudder O.

From the foregoing it will be seen that the boat is propelled withoutany special machinery and in a very simple manner, it being understoodthat the boat may be run for quite a long time, according to the amountof gas generated in the hull and the size of the minute outlet-pipe D,through which passes the liquid forced out of the hull by the pressureof the gas. I

I do not limit myself to any special substance used for generating thegas; but it is evident that sodium carbonate or bisulfate of soda orsimilar substance may be employed and placed on the shelf F, and then anacid or an acid salt is added to the substance to generate gas in thehull, for the purpose above mentioned. V

Having thus fully described-my invention, I claim as new and desire tosecure by Letters Patent 1. As a new article of manufacture, a toy boathaving a hull adapted to be partly filled with a liquid, a minutedischarge-pipe lead ing from the bottom ofthe hull and a sup.- portarranged within the hull above the surface of the liquid and adapted tosustain gasgenerating chemicals, whereby the gas generated within thehull will press upon the surface of the liquid and force the same out ofthe discharge-pipe to propel the boat, substantially as described.

2. As a new article of manufacture, a toy boat consisting of a closedhull adapted to be partly filled with water, a minute dischargepipeleading from the bottom of the hull in a rearward direction in alinementwith the keel of the boat, a transverse shelf located within the hullabove the surface of the liquid and adapted to sustain chemicals forgenerating gas, and a filling-opening in the top of the hull directlyabove the said shelf and normally closed by a screw-plug, substantiallyas shown and described.
